Tadalista Super Active, the most reliable approach is to have the product checked by a licensed pharmacist or a government-authorized drug-testing laboratory. The name on the package alone does not prove what the capsule contains. Who can verify it? A licensed pharmacist: Can check the label, stated active ingredient, strength, manufacturer, batch number and expiry date. This is a useful first step, but cannot prove the capsule's actual chemical contents. The manufacturer or marketing authorization holder: Can provide product documentation and batch-specific quality-control information. Independent verification may still be necessary. A government-approved drug-testing laboratory: Can chemically analyze a sample to identify the active ingredient and measure its quantity. This is the strongest option for verifying the actual contents. A drug regulatory authority: In India, you can contact your state drug-control department or the Central Drugs Standard Control Organisation (CDSCO) for guidance on suspected counterfeit or mislabelled medicines.
